We did this every night. Exercise that it. We did it together to keep us from quitting, if one didn't want to go, the other made them. Usually we just jog around the local park a few times (only at night, we both prefer the dark). However, tonight wasn't a normal work out. About halfway around the park my jogging partner stopped me and told me to follow her. She led me to the middle of the park, and also the darkest, and kissed me.
"What are you doing, Jenn?" She grabbed my hand and put it on her breast, effectively shutting me up, and kissed me again. Something told me I shouldn't just sit there, so I grabbed her ass and pulled me forward. I never noticed how sexy Jennifer was. I had seen her breasts bouncing when she jogged, and heaving when we got back, but I never really paid attention. Now, with one in my hand, I squeezed it, and played with the nipple through the fabric of her shirt, coming to the conclusion that her breasts were easily a C-cup. Her ass was thick, and full, and she really seemed to like it when I rubbed it.
OK, reality check. Here I am, tongue down the throat of a beautiful woman...my jogging partner for God's sake! I've been jogging with her for over 4 months and never noticed how sexy she was. I couldn't let the opportunity get away from me, so I massaged her ass even more, making her grind her hips against my erection. The more I played with her tit and ass, the more she rubbed her pussy against me. After only 2 minutes, she began moaning in my mouth. I couldn't believe it, she was cumming. Jennifer was really humping me now, and through my pants. Her moans became squeals, her squeals became screams, as she ground her pussy against me, bringing herself to orgasm.
